The Secret of Filling Machine

In the production line, the filling machine plays a crucial role, and the choice of its material directly affects the performance and service life of the filling machine. The corrosion resistance, stability and durability of the material are the three key factors to consider when choosing.

Corrosion resistance is particularly important for filling machines, especially when in contact with all kinds of chemical liquids, food and other corrosive materials. Stainless steel has become a common material for filling machines because of its excellent corrosion resistance. For example, SUS304 stainless steel is not only heat and corrosion resistant, but also has good plasticity, easy to process and form, and is widely used in the production of filling machines. The teflon material has an excellent performance in anti-corrosion, and is often used in parts such as filling guns to enhance the anti-corrosion performance of the machine when filling strong acid and alkali materials.

The application of different materials in filling machines

Stainless steel, especially model 304, has become one of the most commonly used materials in filling machines for its excellent corrosion resistance and high temperature strength. It not only has good plasticity, easy to manufacture a variety of complex structures, and its smooth surface is easy to clean, in line with the requirements of food hygiene and safety. Therefore, stainless steel is widely used in the body of the filling machine, pipes and valves and other components.

316 stainless steel adds 2-3% molybdenum on the basis of 304, which has stronger corrosion resistance, especially in some specific media. Therefore, 316 stainless steel is often used in parts that come into direct contact with food, such as the filling nozzle of the filling machine, to ensure higher hygiene standards ‌.

Heat resistance is also an important factor to consider when selecting materials. 316 stainless steel has good oxidation resistance at low temperatures and is suitable for high temperature environments. 304 stainless steel shows good heat resistance when used in a certain temperature range, but after a certain temperature range, its performance will be affected ‌.
